When I was a teenager, I don't think I ever imagined doing anything other than playing video games and eating junk food. Luckily, these teenage girls weren't me because they've developed a generator that can be powered with urine. Yep, it's pee-powered.

Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin and Bello Eniola are 14 and 15-year-old kids from Nigeria who've cooked up a system where 1 liter of electricity can get you 6 hours of electricity. That's the best use of pee I can think of. Here's how it works:

Urine is put into an electrolytic cell, which separates out the hydrogen.

The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.

The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
